BROMINATED FLAME RETARDANTS IN HOUSE DUST FROM THE PHILIPPINES:LEVELS, PROFILES AND FATE
House dust samples (n=20) from Payatas a waste dump site, and Malate a reference site in the Philippines were collected in 2008 and analyzed for two brominated flame retardants (BFRs), viz., polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecanes (HBCDs). Concentrations of PBDEs found in house dust (mean: 665 ng/g dust) were significantly higher than HBCDs (mean: 22 ng/g dust), which is concomitant with the difference in the historical usage of these two BFRs. Overall mean concentrations of PBDEs found in our study were higher than those in Indonesia, Finland, Kuwait and Denmark, but several orders of magnitude lower than those in Canada, US and UK. On an average the major congeners detected in house dust samples were BDE -209 followed by -99, -47, and -183. Among HBCDs, α- and γ- HBCD were the predominant isomers in both locations. The extent of contamination varied between homes because of the different set of circumstances in every microenvironment. House dust may be regarded as the most important exposure route of PBDEs and HBCDs for children. This study was the first of its kind to be conducted in the Philippines to measure concentrations of BFRs in house dust.
